Error installing paramiko using pip

Question

I am trying to install paramiko using pip. It shows the following long list of error messages after installation. The message here Details here .

Running pip freeze show the paramiko package on the installation list but it is not working.

Trying to run a simple paramiko program shows following error again

Traceback (most recent call last):
  File "paramikoBasic.py", line 1, in <module>
    import paramiko
  File "/home/tara/taraproject/scripttest/paramiko_test/myenv/local/lib/python2.7/site-packages/paramiko/__init__.py", line 30, in <module>
    from paramiko.transport import SecurityOptions, Transport
  File "/home/tara/taraproject/scripttest/paramiko_test/myenv/local/lib/python2.7/site-packages/paramiko/transport.py", line 33, in <module>
    from cryptography.hazmat.backends import default_backend
ImportError: No module named cryptography.hazmat.backendsled 

I even tried to install cryptography separately but that even didn't solve the problem. Installed libffi too but that also didn't work out.

Answer 1

I am guessing you are using ubuntu since it's a common problem The cffi module is dependent on libffi and libffi-dev .

If you search for current version using

apt-cache search libffi

you should be able to get latest version.

Currently you can install as
sudo apt-get install libffi6 libffi-dev

Also you need to install python-dev and crypto packages as logs indicates.
